EC 1.3.3.15 Details

show Brenda entry

EC number

1.3.3.15

Accepted name

coproporphyrinogen III oxidase (coproporphyrin-forming)

Reaction

coproporphyrinogen III + 3 O₂ = coproporphyrin III + 3 H₂O₂

Other name(s)

hemY (gene name)

Systematic name

coproporphyrinogen-III:oxygen oxidoreductase (coproporphyrin-forming)

Comment

Contains FAD. The enzyme, present in Gram-positive bacteria, participates in heme biosynthesis. It can also catalyse the reaction of EC 1.3.3.4, protoporphyrinogen oxidase, at a lower level.
